Possible Causes

Faulty temperature sensor reading too warm, Stuck compressor relay on control board, Poor door seal causing constant heat gain, Ambient temperature too high

How to Fix / Troubleshooting

Safety: Unplug before inspecting electrical components.

  • Check actual temperature: Use a thermometer to see if the cabinet is below the setpoint. If so, the control is not sensing correctly.
  • Inspect gasket and door usage: Replace damaged gaskets and reduce door openings.
  • Test thermistor: Verify the cabinet sensor resistance vs. temperature. Replace if out of spec.
  • Control board relay: Inspect the compressor relay on the main board for signs of sticking or heat damage. If the compressor remains on even when the board should be off, replace the main control board.

Continuous running increases wear and energy use; address promptly.
